- To all whom 'it may concern:I

Be it known that I, IRVIN M. RHoAnns, a citizen of the United States, residing at Racine, in the county of Meigs and State of Ohio, have invented new and useful fmprovements in Mud and Scale Collectfs to be Used in Any Type of Horizontal Steent- Boilers, of which the following is a speciiication. y

This invention relates to improvements in `'mud and scale collectors, for use in steam boilers, to prevent. the settling of mud and to also prevent the accumulation of scale in `of the saine,v showing the mud collector or'." skimmer in plan and with its covering wingerI open and extended from opposite sides.

boilers and for discharging the mud and scale, by boiler pressure from time to time.

One object of my invention is to efect improvements in the construction of the collector whereby the same, is provided with, a cover which may be opened and used 1nv the invention consists inthe construction,y

combination and arrangement of devices hereinafter described and" claimed. 4

In the accompanying drawings:-Figure 1`-s a vertical longitudinal sectional view. cfa-steam boiler provided with mudand sediment collectors or skimmers constructed and arranged in accordance with my invention. Fig. 2 is a horizontal sectional view Fig. 3 is a vertical transverse sectional view of the same. Fig. 4 is a detail sectional view on a larger scale.

The boiler 1 is here shown as a horizontal 'i boiler, provided with flues 2. The mud col lector or skimmer 3 is arranged above the ue and the sediment or scale collector 4 is arranged below the'i'lue and is provided with supportin legs 5 which bear on the bottom of the. oiler, the mud collector 3 being providedwith ianges 6 which bear on the upper lu'es. Otherwise the collectors are identical in construction. Each collector comprises abodyand la-cover. The bdy 7 is here shown as semi-cylindrical in form and the cover is shown as comprising a pair of quarter or cylinder-segment members 8 which are connected to opposite sides of the. 1Body 7 by hinges 9 so` that they can be closed over the body or opened and extended outwardly therefrom in opposite directions to form skimming wings which serve to skim the mud particles from the water inthe upper portion of the boiler and to collect the 'sediment from the-water in the lower portion of the `,boiler and hence prevent the accumulation of mud and the s'cale in the boiler, and also prevent bagging.

A -feed water pipe 10 is connected to a pipe 11 which leads to one end of the bodyvof the mud collector, the body of the/mud collector being ,provided at the opposite end with an opening 12 the diameter of which is greater than that of the pipe 11. A11 exhaust pipe 13 may be put in communication with the pipe 11 by means of a three-way pipe to be put in communication with the said pipe 11 and also enables the said pipe to be closed. p

The operation of-the mud collector is as cock 14 which also enables the feed water l follows c--When the covering and skimming 'wings 8 are open and extended and the boiler is in operation, the feed water pipe is connected to the pipe 11 by the three-wayl cock 14 and as the feed water passes into the ,boiler from the bodv and over the covering Wings of the mud cbllector, the mud particles are skimmed and collected from the I water and caused to settle in the body and in its covering and skimming wings. At suitable intervals of time the wings or covering elements 8 are closed over the body ,and the pipe 11 is disconnectedyfrom the feed water pipe and connected to the exhaust pipe 13 by the valve'14, thus causing water and steam from the boiler, at boiler pressure, to enter the collectorv through the opening 12 and to discharge and blow-off all the mud collected therein.

The scale collector 4 which otherwise operatesin. the same manner as the mud co1- lector, is entirely disconnected from the feed water pipe 10 and is provided at the end opposite itsvopening 12 with a blow-oit or discharge lpipe 15 which'is provided with a 'i suitable rvalve 16.v

I .'will: now describe my improved means for operating the coversof the 'collectors and opening and closing them. A verticalshaft 17 which is common to both the collectors passes' through an opening in the center of the bottom of the mud collector and has its lower end mounted in a bearing in the center of the bottom of the sediment or scale collector as shown. Chains 18 are attached to the said shaft and to the outer side of the collector Wings or covering ele- Inents, to be Wound on said shaft and close said Wing or covering element over the bodies of the collectors when the shaft is turned in one direction, and chains 19 are .attached to said covering or Wing elements 8 and to the shaft and engage direction pulleys 20 mounted in openings in the sides of the bodies ofthe collectors, said chains 19 being.\vound on said sha'ft When the latter is turned in the reverse direction and caused to open said cover and skimming elements 8 as will be understood. Hence the shaft 17 is a-common operating shaft for the covers for bothjnof the collectors and serves to open or close the same simultaneously.

A hand Wheel 21 is provided at the upper end ofthe shaft to enable the same to be turned. A bearing bracket 22 is provided on the boiler for the upper portion of the "shaft and a packing box 23 is also provided therefor.

from the spirit of the invention and Within Y the scope of the appended claims.

Having thus described my invention, l claim 1. A collector of the class described for skimming element pivotally connected thereto at one side and adapted to be extended/ from the body or to be closed over the same and used as a cover therefor, and means to arrange said skimming element in open or closed position.

2. A collector of the class described, for use in a boiler, and comprising a body open at its upper side and a skimming element extending from one side, of the body.

3.,A collector of the class described for use in a boiler, an'd comprising a body and a skimming element pivotally connected thereto at one side and adapted to be extended from the body, or to be closed over the same and used as a cover therefor.

- 4; A/boilcr, a collector therein, a pipe leading to the collector,` a feed water pipe, an exhaust pipe, both coupled to the first named pipe, and a valve to put the first named pipe in communication with either the feed -water pipe or the exhaust pipe.

5. A boiler, a plurality of collectors therein and each comprising a body and covering means therefor adapted to be arranged in open or closed position, and common operating means for the covering means of the collector.

6. A collector of the class described for use in a boiler and comprising a body and skimmingand covering means pivotally con-l nected to opposite sides of the body, anoperating shaft, flexible closing means connected to said Wings and shaft for winding on the latter when the shaft is turned in one direction and flexible opening means connected to the Wings and shaft for winding on the latter when the shaft is turned in the reverse direction.

In' testimony whereof I affix my signature in presence of two Witnesses.
